Figure 38 WiMAX: Multiple Mobile Stations
A base station's coverage area can extend over many hundreds of meters, even under poor
conditions. A base station provides network access to subscriber stations and mobile stations,
and communicates with other base stations.
7.2.1 Authentication
When authenticating a user, the base station uses a third-party RADIUS or Diameter server
known as an AAA (Authentication, Authorization and Accounting) server to authenticate the
mobile or subscriber stations.
The following figure shows a base station using an AAA server to authenticate mobile station
MS , allowing it to access the Internet.
Figure 39 Using an AAA Server
In this figure, the dashed arrow shows the PKM (Privacy Key Management) secured
connection between the mobile station and the base station, and the solid arrow shows the EAP
secured connection between the mobile station, the base station and the AAA server. See the
WiMAX security appendix for more details.
